在Woocommerce中获取当天的订单总购买金额

Question

对于Woocommerce，我在下面编写了代码，试图获取今天的订单总购买量：

function order_total_woo_fahad(){
// Get orders from people named John that were paid in the year 2016.
$orders = wc_get_orders( array(
'date_paid' => '2018-07-03'
) );
$total_of_all=0;
for($i=0;$orders[i];$i++)
$total_of_all= $orders[i]->get_total();
return $total_of_all;
}

但它返回空值。

我做错了什么？如何获取当天的订单总购买金额？

Answer 1

获取它的最佳和有效方法是使用以下非常轻的SQL查询，它将获取过去24小时内"正在处理"和"已完成"订单状态的所有订单总数的总和：

function get_daily_purchases_total(){
global $wpdb;
return $wpdb->get_var( "
SELECT SUM(pm.meta_value)
FROM {$wpdb->prefix}posts as p
INNER JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
WHERE p.post_type = 'shop_order'
AND p.post_status IN ('wc-processing','wc-completed')
AND UNIX_TIMESTAMP(p.post_date) >= (UNIX_TIMESTAMP(NOW()) - (86400))
AND pm.meta_key = '_order_total'
" );
}

代码进入函数.php活动子主题(或活动主题(的文件。经过测试并工作。

>USAGE 示例- 显示每日总购买量：

<?php echo '<p>Total purchased of the day: ' . strip_tags( wc_price(get_daily_purchases_total() ) ) . '</p>'; ?>

如果您想根据"今天"日期获取总数，您将在代码中替换以下行：

AND UNIX_TIMESTAMP(p.post_date) >= (UNIX_TIMESTAMP(NOW()) - (86400))

通过这一行：

AND DATE(p.post_date) >= CURDATE()

<?php
global $wpdb;
$date_from = '2015-11-20';
$date_to = '2015-12-20';
$post_status = implode("','", array('wc-processing', 'wc-completed') );
$result = $wpdb->get_results( "SELECT * FROM $wpdb->posts 
WHERE post_type = 'shop_order'
AND post_status IN ('{$post_status}')
AND post_date BETWEEN '{$date_from}  00:00:00' AND '{$date_to} 23:59:59'
");
echo "<pre>";
print_r($result);
?>
